Description
A new method of correcting dynamic nonlinearities due to the multipole content of a large synchrotron such as the Superconducting Super Collider is discussed. The method uses lumped multipole elements placed at the center (C) of the accelerator half-cells as well as elements near the focusing (F) and defocusing (D) quadrupoles at the ends. In a first approximation, the corrector strengths follow Simpson's Rule. Correction of second-order sextupole nonlinearities may also be obtained with the F, C, and D octupoles. Correction of nonlinearities by ∼ three order of magnitude is obtained, and a solution to a fundamental problem in large synchrotrons is demonstrated. 13 refs., 2 figs., 2 tabs
